Development of safe and effective hydrogen storage systems is critical for further implementation in fuel cell technologies. Amongst the various approaches to improve performance such systems, porous materials-based adsorptive envisaged as a long-term solution because excellent reversibility, good kinetics possibility store at low pressures. Metal–organic frameworks (MOFs) have attracted much attention materials transition from laboratory commercial applications. However, MOF are often...

The imperative to address traditional energy crises and environmental concerns has accelerated the need for structure transformation. However, variable nature of renewable poses challenges in meeting complex practical requirements. To this issue, construction a multifunctional large-scale stationary storage system is considered an effective solution. This paper critically examines battery hydrogen hybrid systems. Both technologies face limitations hindering them from fully future needs, such...

Polyethylene terephthalate (PET), a chemically stable polyester with multiple applications, has risen dramatically in manufacturing and consumption the past decades. The increase PET use resulted considerable volumes of waste pilling up thus causing increased health environmental concerns. Apart from landfills incineration solutions, common recycling practices mainly focus on low-value downstream products. All abovementioned factors have contributed to lower overall rate less than 30% South...

Abstract The direct correlation between active sites and catalytic activity in multiple‐component metal‐organic frameworks (MOFs) is key to understanding their mechanism of oxygen evolution reaction (OER) but remains vague. Herein, supported multiple‐site MOFs are adopted as model catalysts quantitatively study the composition‐dependent OER performance. Ni on Fe metal substrate possess highest intrinsic with Ni/Fe ratio 1:2 presence leaching during synthesis. Further introducing a proper...

Abstract Climate change and its related side effects are generating a demand for innovative ways to enhance desalination performance by adopting cost-effective energy-efficient membrane materials. Molybdenum disulphide (MoS 2 ), two-dimensional (2D) material, holds the potential address deficiency of current polymeric reverse osmosis (RO) maximizing water-energy nexus. The nanoscale thickness MoS promises better water permeability benefiting from small diffusion length transport molecules...
